CALIFORNIA PROPOSITION 65 WARNING:
This product and related accessories
contain chemicals known to the State of California
to cause cancer, birth defects or other reproductive
harm.
ELECTRICAL:
1. To reduce the risk of electrical shock, pump must
be properly grounded in accordance with the
National Electric Code and all applicable state and
local codes and ordinances.
2. To reduce risk of electrical shock, disconnect the
pump from the power source before handling or
servicing.
3. NEVER operate a pump with a power cord that has
frayed or brittle insulation.
4. NEVER let cords or plugs lie in water.
5. NEVER handle connected power cords with
wet hands.
PUMPS:
1. Pump builds up heat and pressure during
operation, allow time for pump to cool before
handling or servicing.
2. DO NOT pump hazardous material not
recommended for pump (flammable, caustic, etc.).
3. Make sure lifting devices are securely fastened
each time before lifting pump.
4. DO NOT LIFT PUMP BY THE POWER CORD.
5. DO NOT exceed manufacturer’s
recommendation for maximum performance, as
this could cause the motor to overheat.
6. Secure the pump in its operation position so it
cannot tip over, fall or slide.
7. Submersible grinder pumps are not approved
for use in swimming pools, recreational water
installations, decorative fountains or any
installation where human contact with the
pumped fluid is common.
8. DO NOT pump without safety devices in place.
9. Basin must be vented in accordance with the
local plumbing codes.
IMPORTANT! Myers is not responsible for losses,
injury or death resulting from failure to observe these
safety precautions, misuse or abuse of pumps or
equipment.
Control Panels:
All Myers control panels used on these grinders are
UL listed and CSA certified. Control panels mounted
directly to the basin used outdoors are UL listed and
CSA certified waterproof.
If intrinsically safe controls used in hazardous locations
are required, Myers can furnish an UL listed or CSA
certified panel. Otherwise the installer must obtain a
source for the panel required.
Level Sensing Controls:
Intrinsically-safe type float controls are recommended
for all applications and required for hazardous location
service. An intrinsically safe control panel relay will limit
the current and voltage to the level controls. A Myers
control panel can be supplied with this type circuitry.
The float level controls maintain the basin sewage
water level by controlling pump turn-on and turn-off
level.

1. The lower turn-off control should be set so that the
pump stops at approximately the top of the pump.
2. The upper turn-on control should be set above the
lower turn-off control. The exact height between
the two controls is determined by the number of
pump starts desired and the depth of the basin.
A maximum of 10 starts per hour should not be
exceeded.
3. The override control is set at a specified height
above the upper turn-on control.
4. The alarm control is set about 6" to 12" above the
override control.
5. No control should be set above the inlet invert.
Junction Boxes:
If a junction box is used in a hazardous location, it
must be a hazardous location approved type with
hazardous location cord connectors. Wires from the
junction box must pass through a hazardous location
seal connector.
CAUTION – No persons should be in the basin when
pump is lowered into position! DO NOT lift pump in a
manner where any failure could result in loss of life.
Air Venting:
Air tends to trap in the pump volute when water raises
in the sump or when the pump is lowered into water
after service. To vent off this air, a small hole is drilled
into the pump volute. Be sure this vent hole is clean
after any service work on pump.
USAGE – The TPL15 grinder pumps are for pumping
domestic sewage. These pumps are not to be used for
pumping commercial or industrial sewage from motels,
schools, apartments, factories, etc.
PUMP MODELS – The TPL15 pumps are equipped
with 230 volt single phase motors with seal leak
detector.
CAUTION – PUMP IS ONLY TO BE DISASSEMBLED
AT MYERS FACTORY OR AN AUTHORIZED MYERS
SERVICE FACILITY.
DESCRIPTION OF PUMP – This pump is intended to
grind and pump all normal sewage for home use.
Pump is of heavy duty construction, and submersible
type for long life when pumping ground sewage. Motor
is capacitor start, capacitor run for single phase.
Capacitors and start relay are mounted in the electrical
control box. All single phase motors must have special
electrical control box furnished by Myers.
INSTALLING SINGLE PHASE MOTORS WITH
CONTROLS OTHER THAN MYERS VOIDS
WARRANTY.
CAUTION – After pump is installed NEVER WORK
ON MOTOR OR GRINDER UNIT WITHOUT
DISCONNECTING MOTOR LEAD WIRES FROM
CONTROL PANEL. DON’T RELY ON OPENING
CIRCUIT BREAKER ONLY.
Pump has two oil-filled chambers — 1) the motor and
ball bearings and, 2) the seal chamber—for long life
and best heat transfer.
The lower seal above the pump impeller acts as
a buffer for upper seal that holds oil in the motor
chamber. If lower seal leaks for any reason, water
enters the seal chamber. If motor has the seal leak
detector, the electrode will contact the water and close
the circuit to the red seal light in the control panel
indicating motor must be serviced before upper seal
fails.
MOTOR OVERLOAD PROTECTION – The motor is
provided with an on-winding overload switch. If motor
overloads or overheats for any reason, the switch
opens stopping motor. As soon as the motor cools to
normal temperature the switch closes and restarts the
motor.
MOTOR POWER CORDS – Pump models with seal
leak detector use a 5 conductor cord. The three power
conductors are BLACK, WHITE, RED, the BROWN
conductor connects to the seal leak probe and GREEN
conductor connects to the ground screw inside the
cord cap.
CORD SEAL – The lines from the motor chamber are
sealed with a rubber sealing grommet that prevents
oil from leaking into the cord cap compartment. If
necessary to replace power cord, the sealing grommet
must not be loosened. This wire seal is removed only
for complete motor repair that must be done at an
authorized motor repair shop.
IMPORTANT – Ground wires must be connected in the
control box to grounding bar, which is connected to a
good outside ground. MOTOR IS NOT SAFE UNLESS
GROUNDED.
SINGLE PHASE CONTROL BOX – Single phase
pumps must use the Myers control box. Warranty is
void if other than Myers single phase control box is
used.
THREE PHASE CONTROL BOX – Any suitable three
phase control equipment can be used for simplex
or duplex operation. These control boxes are also
available from Myers. If other than Myers box is used,
overload heaters must be selected in accordance with
full load amp ratings.
If any amp readings are higher than listed, it indicates
voltage may be higher or lower than normal, or that
pump grinder may be clogged with trash causing extra
load on motor.

TROUBLE CHECK LIST
Troubles listed are generally caused by the pump. Other trouble can occur from faulty control box operation.
These will be listed with the control box instructions.
CONDITION PROBABLE CAUSE
Pump runs but does not
pump liquid from basin
Red light comes on at
control box.
Overload trips at control box
and alarm buzzer or flashing
red light comes on due to
high water level in basin.
1. Pump impeller may be air locked, this occasionally occurs on a new
installation. Start and stop pump several times to purge air.
2. Run additional water into basin so that pump will be submerged deeper to
clear air.
3. If air does not clear, it may be necessary to lift pump out of sealing elbow
and start motor to allow pump to pump for a few seconds. If discharge is
piped in with union, slightly break union and start pump to clear air. Air
vent hole is provided in pump case, so some water will flow from this hole
when pump is operating. If vent hole gets clogged, clean out.
4. If pump has been installed for some time and does not pump, it may be
clogged at grinder inlet.
5. Discharge gate valve may be closed.
6. Discharge check valve may be clogged or have a broken clapper.
7. Discharge head may be too high. Check elevation. Maximum pump head
at zero flow is 70 feet.
8. If above check do not locate trouble, motor rotor may be loose on shaft
which allows motor to run but will not turn impeller or only at low RPM.
1. This indicates some water has leaked past the lower seal and has entered
the seal chamber and made contract with the electrode probe. Pump must
be removed immediately from basin for replacement of lower seal. This
preventative repair will save an expensive motor.
1. Push in on red reset button to reset overload. If overload trips again after
short run, pump has some damage and must be removed from basin for
checking.
2. Trouble may be from clogged grinder causing motor to overload or could
be from failed motor.
3. Trouble may be from faulty component in control box. Always check
control box before removing pump.
Checking For Moisture in Motor: Disconnect line
leads from terminal strip. Use ohmmeter and set on
highest scale. Readings on the large power cord
between any of the conductors red, black, white
to green, or motor housing should be more than
500,000 ohms.
Resistance of Windings: Every motor winding has
a fixed resistance. The windings must check close to
the specification values. This winding resistance also
shows if motor is connected for voltage being used.
Use ohmmeter for this test and set on scale to read
directly in ohms.
CHECK LIST IF PUMP DOES NOT OPERATE PROPERLY

TROUBLE CHECK LIST (Cont’d)
CONDITION PROBABLE CAUSE
Yellow run light stays on
continuously.
Circuit breaker trips
Pump is noisy and pump
rate is low
Grease and solids have
accumulated around pump
and will not pump out of
basin.
1. Indicates H-O-A switch may be in the hand position.
2. Level control switch may have failed causing pump to continue to
operate when water is below lower float.
3. Grinder assembly may be partially clogged causing pump to
operate at very reduced capacity.
4. Gate valve or check valve may be clogged causing low pump flow.
5. Pump may be air logged.
1. Reset breaker by pushing clear down on handle then back to on
position. If breaker trips again in few seconds it indicates excessive
load probably caused by a short in the motor or control box.
2. If this condition happens after an electrical storm, motor or control
box may be damaged by lightning.
3. Resistance reading of the motor with lead wires disconnected from
the control box can determine if trouble is in motor or control box.
1. Grinder assembly may be partially clogged with some foreign
objects causing noise and overload on the motor.
2. Grinder assembly may be rubbing on grinder ring due to bent shaft
or misalignment.
1. Pump “ON” switch may be set too high.
2. Run pump on hand operation for several minutes with small amount
of water running into basin to clean out solids and grease. This
allows pump to break suction and surge which will break up the
solids.
